per ends, at i 9, their freeends depending downward and terminating at a point at short distunce above the plate 15, as seen in- Figs. '1, and 7. As seen best in Fig. 6, these springs rise from. the plete at oints be tween the flanges 16, the springs ieing unconlined by the inturncd flange or rim of the base, but, at the junction oi their inner sides with the base, strengthened and reinforced by the inwardly pressed portions 20, as seen clearly in 6 and 7.

Rising eontrully from the base 11 is on uxinl tube 21, seen best in Fig. 7, end at the upper end of this tube is 2. horizontal plate 22 which embraces said tube. Said plate is shown l'iexi'igonel in form, every other side being, formed with a tongue 23 engaged in openings in the inner} vertical portions of the springs, as seen clearly in Figs. 3 and 7, so as to stiffen and reinforce the springs near their upper endsiind also to hold-in place the upper free end of the tube. The upper end of the tube 2i. isshown as rovided with in Werdly inclined projecting ips 2 L whichenin e groove 25 in the upper end of the spindle or pin. 10,- so as to normally hold the some against disnleeenient.

in Fig. 7, 2t designates the lower end of a hollow leg of e oeiiin which the cooperating portion of theeester'is shown {LS engaged, it being understood that the outer members of the springs are received therein end frietionidly engiiged with the inner surface of such holiow in Figs. 8, 9 end 10 l have shown aslightly modified form. of my caster hut embodying substmitiull the same principles and ed entiiges, thot is so for its pertuins to the upper in this form the Wheel may be of at construction similar to that herein before de- 'WOOdfiYl Wheel or any other form suited to the purpose. in this form, however, in lieu of the halls 33, the plate 2-7 is formed with downwardly extending protuhermices 28 Whichrest at their lower ends in {L circular groove 29, in the upper lure of the hose 9 of the 'yolrie oi the ouster, the side portions 8 reeeiving the axle 5, the some as in the con struetion above desiribed. The action and result are substantially tl some as in the form )roviously described.

Moi ilicutions in detail may be resorted to Without departing from the spirit of the in motion or sacrificing on of its r' lvuntuges.

No churn inn-dc in this upplicution to the construction of the Wheel per .90 :isthe some. Wlil lOl'Ill. the subject-mutter of u sepinute upplicution to be iiled us it division hereof.

i l nat is claimed as new is:-

. i 1 1. In a caster, a. plate, springs rising therefrom, and means adjacent the up er ends oft the springs for stiffening and re 'orcing the some.

2. In a caster, a late, springs rising therefrom, and an axially supported. piste near the upper ends of the springs having tongues received in openings in the inner members of the s rings.

n a. caster, a plate, s rings rising therefrom, an axially supported plnte near the up per ends of the springs having tongues re ceived in openings in the inner members of the springs, and on axial tube received inand supported by said plate:

4. In it caster, e bzise having downwardly projecting parts, bulls in said parts, a. plate hearing on the upper surface of the balls, 21. plate resting on said plate and formed with spring arms hent upon tin-resolve the upper peripheral edge of the hose be 11g turned inward over said plates, and the springsreh'iforced at their junction with the plate.

5. In it easier, a hose having downwardly projecting parts, halls in said parts, a. plate hearing on the upper surface of the balls,'a plate resting on said plate and formed with spring arms bent upon themselves, the u. per peripheral edge of the base being turner in u'iird over said plates, and the springs reinforced at their junction with the plate, and

means for stiii'ening and reinforcing the upper ends oi the springs.

(i. In :1 ouster, abuse having downwardly )rojecting parts, halls in said pin-ts, a plate ouring on the upper surfuoe oi' the balls, a plate resting on. said plate and spring urins bent upon themselves, the upper peripheral edge of the base being turned inward over said plates, and the springs reini'oreed at. iheir junction with the plate, means for still'cning and reinforcing the upper ends of the springs, and an axial tube risingfrom the base and received in and supported by said stil'lening and reinforcing,inesns.

7. in :1. ouster, o. wheel-suppi- ,mgyoke, a

base plate with axial tube. spit disposed formed with i about said tube, anti-frictionbenrings be.

tween said plute and the nose of the yoke and means for still'ening the upper ends of mid springs.

in witness whereof, I have hereunto set iruluurd this. 8th day of January, 1909. in the presence oi two subscribing witne ses. BENJAMIN (I M'A'll HES. Wit nessvs: l]. l). il nrnonn. .i. t- ..vi'ili"rnoun.
